Abstract (en)
This uninterruptible power supply includes: a cooler (6) that dissipates heat of a converter (1) and an inverter (5); and a controller (8) that causes, when output power (Po) from the inverter (5) exceeds an upper limit value (PoH), reduces input power (Pi) to the converter (1) by power (ΔPo = Po-PoH) corresponding to a difference between them, and increases input power (Pb) to a bidirectional chopper (4) by power (2×PoH) that is twice as high as the power (ΔPo) corresponding to the difference.
